A Tae Kwon Do instructor in Springfield is facing charges involving child pornography and sexual contact with two minors who were previously students at his martial arts school, according to Fairfax police.

Police announced Wednesday that 38-year-old martial arts instructor Quyen Vinh Phan Le was indicted Monday on three counts possession of child pornography and four counts of indecent liberties with a minor by someone in a supervisory relationship.

In June 2011, one victim reported having sexual contact several times with Mr. Quyen both at his martial arts school, Phan University of Martial Arts, and at his home. Police said that occurred between May 2003 and January 2005 while the victim was a minor.

As detectives were investigating the allegations of the first victim, they met with another woman who said that in late 2008, when she was also a minor, she had sexual contact with Mr. Quyen.

According to information on the Phan University of Martial Arts website, Mr. Quyen is the master instructor at the school and has taught martial arts in the Springfield area for 15 years.
